 Introduction:
Coal or biomass fuel thermal oil boiler is a new type of heating equipment, with coal, oil, gas, biomass as fuel and flue gas as heat source, heat conduction oil (such as L - QB, L - QC, L - QD, etc.) as the heat carrier, through the circulating pump to force heat transfer medium to circulate in liquid phrase , and transfer heat to heat user equipment, then return to the heating furnace for re heating high temperature, low pressure, energy-saving equipment. Heating temperature can be as high as 340 ℃, and generally under working pressure of 1.1MPa, because of working in liquid state, safe and reliable.

Application Scopes

Owing to its characteristics of high heating temperature , low working pressure ,energy saving, thermal oil boiler can be widely used in a variety of industrial heating process. Instead of electricity, steam heating, and it can improve the productivity.
1. Paper industry: dry, corrugated paper processing, calender, glue roller.
2. Wood industry: plywood, density board, hot pressing molding, wood drying, steaming equipment.
3. Building materials industry: plasterboard drying, asphalt heating, emulsified asphalt, asphalt concrete, concrete component maintenance, drying equipment, linoleum production line.
4. Machinery industry: spray drying of printing, assembly processing, dry cleaning.
5. Food industry: baking bread and baking cookies, cooking pot, autoclave, conveyor dryer.

Characteristics
1. Strong adaptability of different fuels
    Separated design for combustion equipment and upper furnace, according to the different nature of the solid fuel, furnace can be design individually .
2. Highly degree of grate automation
    The structural grate is full automatic chain grate .
3. Large diameter combustion chamber.
    Boiler combustion chamber is composed of vertical large diameter circular tube, large fuel combustion space, complete combustion, high thermal efficiency.
4. Best coil design .
    Furnace internal and external spiral coil is made of bulls, small diameter steel pipe coil thermal expansion of good performance, low stress, safe and reliable.
5. The optimal process design
    Three return flue gas, medium flows through the inside and outside coils, with uniform velocity, safe and stable operation
6. Sufficient output.
    Reasonable heating surface layout, large area, good heat transfer effect, high efficiency, stable output, sufficient.
7. Perfect automatic control measures
    Precision control on outlet oil temperature, multiple protection and control are set on medium temperature, pressure and smoke temperature to ensure safe and reliable operation.
8. Leading technology in automatic control.
    Boiler controller adopts Siemens/delixi electric components, reliable in performance. Controller has three forms: normal, LCD display in both Chinese and English menu, touch
    screen man-machine dialogue remote control.
